LCM means Lowest common multiple i.e. the lowest number which is common multiple of all the three. So,
63 = 3*3*7
21 = 3*7
105 = 3*5*7
Thus, Common multiple will require
3*3*5*7 = 315 , which is the LCM of 63,21 and 105.
63 = 3*3*7
21 = 3*7
105 = 3*5*7
Thus, Common multiple will require
3*3*5*7 = 315 , which is the LCM of 63,21 and 105.
